Revolutionizing Bird GPS Trackers with “YIM” GaAs Solar Cells

This article discusses the advantages of Gallium Arsenide (GaAs) solar cells, manufactured by YIM Space Machinery Ltd, for powering compact, energy-efficient devices like bird GPS trackers, drones, IoT devices, and precision instruments. GaAs solar cells are ideal for applications where small size, low weight, and high power efficiency are crucial.

uHigh Efficiency (30%): GaAs solar cells offer an efficiency of around 30%, significantly higher than traditional silicon-based solar cells (15-20%). This high efficiency means they can generate more power from the same amount of light, making them perfect for devices that require small amounts of energy, like bird trackers or drones, where space and energy are limited.

uPower Output: The cells vary in power output depending on their size, from 7.81 mW for a 5x5 mm cell to 32.81 mW for a 7.5x15 mm cell. While modest, this is sufficient for low-power devices such as sensors or GPS trackers, with flexibility to select the appropriate size based on energy needs.

uVoltage and Current: GaAs cells operate at a standard 2.5V, with current output ranging from 3.13 mA to 13.13 mA depending on size. This variability allows engineers to match the solar cell to the device’s power requirements, improving the autonomy of mobile devices like bird GPS trackers.

uShort Circuit Current Density: With a short-circuit current density of ≥13.4 mA/cm², GaAs cells are more robust under varying light conditions, ensuring reliable performance even on overcast days or at high altitudes—ideal for bird trackers that need to operate in diverse environments.

uLightweight (0.03g to 0.10g): Weighing between 0.03g and 0.10g, GaAs solar cells are exceptionally lightweight, making them ideal for small devices where weight is a critical factor, such as bird trackers, which must not interfere with the bird’s natural behavior.

uHigh-Altitude Applications: GaAs solar cells are particularly well-suited for high-altitude environments, where sunlight is more intense, ensuring efficient power generation in mountainous areas or during bird migrations.

Conclusion: 

GaAs solar cells from YIM Space Machinery Ltd offer significant benefits in powering small, energy-efficient devices. Their high efficiency, lightweight nature, and robust performance under varying light conditions make them an ideal solution for modern precision instruments, wildlife monitoring, and remote devices.
